I was not able to understand the meaning of those lines. Can you elaborate?It's a good diagram. But question is, why GoTG have 5 and GoTG2 have 6 lines?
Rest I understand
Edit: Captain Marvel & Untitled Avengers movie (2019) will certainly reveal at least 2 lines, if not all.
Edit 2: Again went through it. Now feel, it may not be necessarily linking of movies but main characters.
5 Lines from GoTG to GoTG2 meant for Quill, Gamora, Rocket, Groot & Drax.
6 from GoTG2 is the addition of Mantis. Now it makes sense.
